Dozenal, also known as base-12 or duodecimal, is a numeral system that uses twelve as its base instead of the more common base-10 system. In this system, the digits range from 0 to 11, often represented as 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, and B. This allows for more compact representation of numbers and can simplify certain calculations. Advocates of dozenal argue that it offers advantages in fractions and divisibility, as twelve has more divisors than ten. For example, 12 can be evenly divided by 1, 2, 3, 4, and 6, making it easier to work with in various mathematical contexts.
